If you're a fan of BMW, you may know that the history of the Bavarian auto maker's roadsters is much older than Z series. In fact, it even goes back to the pre-World War II period. So if you want to refresh your knowledge about the history of BMW, this short documentary by X-CAR is just for you. So watch it and share the name of your favorite BMW roadster in the comments section below. For me the choice is already made (see picture above).
